A sequential game is {one of|one among|one in all|one amongst|one in each of} excellent data if just one player moves at a time and if every player is aware of each action of the players that moved before him at every purpose. Technically, each data set contains precisely one node. Intuitively, if it's my flip to maneuver, I invariably grasp what each different player has done up to currently. All different games are games of imperfect data.
